CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE AND VEHICLE EQUIPPED WITH SAME

摘要

An ECU (300) for controlling an engine (160) counts the continuous amount of time for which the engine (160) is stopped in a low-temperature environment. When the period of stoppage falls below a predetermined reference value the ECU (300) sets the idle rotational velocity to a first idle rotational velocity, and when the period of stoppage exceeds the reference value the ECU sets the idle rotational velocity to a second idle rotational velocity that is greater than the first idle rotational velocity. Thus, it is possible to prevent resonance in a drive transmission system during idle running, even when the mount that is used for attaching the engine (160) to the vehicle body has hardened due to exposure to a low-temperature environment for a long period of time and the resonant rotational velocity of the drive transmission system, including the engine (160), has changed.
